The challenge of feeding our planet sustainably is more pressing than ever, pushing us to find smarter ways to use available resources. This study looked at using Paullinia cupana peel meal (PCPM) as a new ingredient in the feed of slow-growing broilers. The research found that adding PCPM improved the growth and health of slow-growing broilers, suggesting that it could be a game-changer in sustainable livestock farming.

Livestock sector growth assumptions should be looked at from the perspective of the dynamics in the domestic and global economy, and uncertainties around the driving forces of the transition. This study used the case of Ethiopia to provide an analysis of alternative national development trajectories relating to the prospects of growth performance and urbanisation. It generates insights into the importance of integrating economy-wide and livestock-system models to provide a risk-based approach to the prospects of the livestock sector.

Due to the growing global demand for more sustainably produced animal protein, there is an intensive search for alternative feeds to replace soybeans, which increases the cost of feed due to limited availability in some countries. Black soldier fly shows great potential for substituting soybeans in poultry diets as it is a sustainable and protein-rich alternative to conventional protein sources for broilers. A meta-analysis was conducted to test the hypothesis that it enhances growth performance and can reduce competition for plant protein sources among humans and animals.

We compared Saanen and Saanen × Boer kid meats and found that the Saanen × Boer crossbreed contributes to increased carcass yield and greater acceptance of the meat by consumers. When comparing different slaughter ages (30 and 60 days), we observed that the carcass fat content increased and lipid oxidation in the meat decreased when the kids were slaughtered at 60 days of age.

Long-term production efficiency gains and changes to production have significantly improved the environmental performance of Australian pork over time. This study was a long-term trends analysis of Australian pork between 1980 and 2022 and found that greenhouse gas emissions and freshwater consumption fell by 74% and 90% over the analysis period. Although novel low carbon production systems were identified, the rate of environmental improvement was found to have slowed since 2010.

Ewes and lambs are often temporarily separated during daily management. This study showed 1 h temporarily ewe-lamb sensory separation affected stress-related behaviours of Small-tailed Han ewes. The ewes showed more exploring or urinating behaviour when separated through lack of tactile contact only with lambs. It suggests that when ewes are temporarily separated from their lambs, avoiding the ewes hearing and seeing the lambs may partially reduce their stress response, thereby improving ewe welfare.

The use of alternative foods, as well as additives that improve the use of these foods for birds, is an area of study that is constantly growing owing to the constant search for ingredients that make feed cheaper. Several studies have already used Moringa oleifera as an alternative food in poultry diets; however, studies that combine this food with exogenous enzymes, additives that can improve its use and bring benefits to the animals’ health, are still almost non-existent.

Coat colour plays an important role in heat tolerance of livestock, because dark coat colour may increase animal heat stress as a result of higher absorption of solar radiation. We focused on the influence of head pigmentation of Boer goats and found light brown-headed animals to be more efficient in eliminating the solar heat gained during outdoor grazing when returned to the shade. In view of global warming, breeding for light coat colour in domestic ruminants could alleviate heat stress.

There is great availability of dried distiller’s grains (DDG) for ruminant feeding in Brazil, but little information on their utilisation. Lambs showed low acceptance of DDG, even at the lowest level of dietary inclusion (150 g/kg DM), as DMI was impaired. Feeding DDG decreased ADG and the carcass traits of feedlot lambs. This research showed the need for further studies on feeding lambs with other types of Brazilian DDG.

In sheep farming, understanding energy needs is important to improve productivity and maintain health. Our study found that male Djallonke sheep in Africa have higher energy requirements for maintenance than previously thought, challenging existing guidelines from national research councils. These findings suggest the importance of updating diet formulations and feeding practices for Djallonke sheep, potentially enhancing the efficiency of sheep farming in the region.
